The method of forming guards or grills combeing formed by the pressing of a single sheet prising the pressing of a sheet metal blank to 70 metal blank. Inasmuch as each bar is provided form a series of parallel bars of U-shaped cross with a pair of flanges and as the depth of each section and of a predetermined depth with an flange approximately equals the space between integral connecting portion at the ends of said adjacent bars, it is obvious that there would be bars, and in crimping said connecting portion insufficient metal in a blank, the original Width of intermediate the bars to reduce the width thereof 75 which was equal to the width of the pressed and to obtain the desired spacing between parts. structure. 011 the other hand, if the blank is of 2.
